Introduction
This volumetric flow rate calculator is designed to help you quickly and accurately calculate the volume flow rate using the Bernoulli Equation.
Calculation
Calculating volume flow rate requires the pipe diameter (d) and the flow speed (v).
⬇️ Inputs
Pipe Diameter (d)
:0.2
Flow speed (v) (m/s)
:10⬆️ Output
Volume Flow Rate (q)
:0.31
Explanation
In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.
The Bernoulli equation states that
where;
The principle is only applicable to isentropic flows. The equation is not valid when the flow is turbulent (the effect is irreversible) and for non-adiabatic processes (e.g. thermal radiation) because the effect is small.

Bernoulli equation can of course be rearranged to solve for each variable. Below presents a calculation to solve for q.
